It makes little sense for Daniels to send T'Pol and Archer. Archer makes an attempt to justify this by saying he is in a hurry and it takes time to get clearences and such, but as T'Pol points out, Daniels can take as long as he likes! Even if he takes the next ten years to get his clearences, he can go back in time to the exact same point Archer and T'Pol arrived at.

Also, Daniels claims that the changes in the past haven't reached the future yet. But every single time we've seen the past changed, the present/future (which word you use depends on your viewpoint) changes instantly. This includes the episodes Daniels has been involved with, so we can't claim he is using some different type of technology or anything.

Great Moment :

Archer ordering burgers. I don't know why, but the incessant requests for super-sizing and adding fries in this scene just struck me as funny.

Body Count :

Three Xindi reptilians killed.

Factoid :

Leland Orser, who plays Loomis in this episode, also played Dejaren in Voyager's "Revulsion", Colonel Lovok in Deep Space Nine's "The Die Is Cast" and Gai in Deep Space Nine's "Sanctuary".

We get a new distance from Earth in this episode - the ship is currently 90 light years away according to T'Pol.

Plotline

Archer is contacted by Daniels, the agent from the future. Three Xindi have been detected on Earth in the year 2004, and Archer and T'Pol must go back in time to find out what they are up to.
